We wouldn’t begrudge you a Grand Opening celebration even when you’ve been open for a while, and especially not when it’s for a good cause. And really not when there are policemen and an alderman involved. All of which is to say, some of Chicago’s finest will be engaged in a burger-eating contest tonight at the (pretty new) upscale burger bar 25 Degrees, to benefit a range of charities including the Chicago Police Memorial Foundation, which aids families of killed or injured officers, Officer Al Porrata who has stage-4 cancer, and the Greater Chicago Food Depository. The eating contest kicks off at 7:30, emceed by ABC 7 sports announcer Jim Rose and with the first burger being eaten by Alderman Brendan Reilly of the 42nd Ward. Attend, eat a burger, and buy $10 raffle tickets to show your support for the boys in blue and these worthy causes.
